Isobaric vapor−liquid equilibrium data for pure components as well as binary mixtures of 2-ethoxyethanol−2-ethoxyethyl acetate was generated using a modified ebulliometer. Measurements are reported for five different pressures in the range of (53 to 101) kPa. Pure component vapor pressures were correlated using the Antoine correlation and compared with the literature data. Binary mixture isobaric data was modeled using the Margules 2-suffix, Margules 3-suffix, van Laar, Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC) equations. Deviation plots for experimental and predicted temperatures are given.

Isobaric vapor–liquid equilibrium data for pure components cyclopentyl methyl ether (CPME) and cyclopentanol (CP) and their binary mixtures was generated using a modified ebulliometer. This data has been reported for five different pressures in the range of 71.50 to 101.79 kPa. Pure component boiling points were correlated using the Antoine equation and compared with the literature data. Binary vapor–liquid equilibrium data was modeled using Wilson, NRTL, and UNIQUAC models. Deviation plots for experimental and predicted temperatures are given. UNIQUAC and NRTL model predictions showed a better fit with the experimental values relative to the Wilson model.

Boiling points for 1,2-dichloroethane and 1-butanol were determined, and P−T−x data for the binary mixture were measured under isobaric conditions using a modified ebulliometer in the pressure range of (101.325 to 60.0) kPa. The pure component experimental vapor pressure data were modeled using Antoine, Wagner, and Thomas models and compared with the literature values. The modeling of binary VLE data was done using Margules 3-suffix, Wilson, and NRTL models. The average RMSD(T) values based on the literature and model predictions for the pure components are in the ranges of (0.42 to 0.47) K and (0.03 to 0.08) K, respectively. Similarly, for the binary system the average RMSD(T) value based on the model prediction is 0.33 K.
